Progressively encoded DVDs in TMPGEnc?

[Xoanon]

I always assumed you had to encode using interlaced video with interlaced encoding checked in TMPGEnc. However, time after time I read DVD reviews where it is mentioned how good the "progressively encoded" transfer is.

Is it wise to do this, I thought the DVD specs could only include interlaced material? If its OK to do it, how do I encode my materials?

Lets say I export a movie (deinterlaced) from Adobe Premiere. Do I:

1) Import this deinterlaced footage into TMPGEnc and choose "non-interlace" under Encode mode on the first settings screen?

2) Import the deinterlaced footage but under Encode mode select "interlace"?

3) Import interlaced footage, but deinterlace using TMPGEnc and then choose "interlace" for Encode mode?

4) Import interlaced footage, but deinterlace using TMPGEnc and then choose "non-interlace" for Encode mode?

Thank you for your help.

In this case, you would choose:

--> 1)

otherwise..


1) Import this deinterlaced footage into TMPGEnc and choose "non-interlace" under Encode mode on the first settings screen?

yes, but you would tick *both* to [non-interlace ] (both tabs)


2) Import the deinterlaced footage but under Encode mode select "interlace"?

no.


3) Import interlaced footage, but deinterlace using TMPGEnc and then
choose "interlace" for Encode mode?

if you want to let TMPGenc do this, then:

..\Video TAB\Encode mode: [Non-interlace ]
..\Advanced TAB\Video source type: [Interlace ]


4) Import interlaced footage, but deinterlace using TMPGEnc and then choose "non-interlace" for Encode mode?

same as 3) also..

if you want to let TMPGenc do this, then:

..\Video TAB\Encode mode: [Non-interlace ]
..\Advanced TAB\Video source type: [Interlace ]

So its actually fine to encode progressive footage for DVD?

BTW, shouldn't your method for #4 be different? Its the same as #3.

It is fine to encode progressive footage for DVD. However, you must remember that commercial DVDs usually come from prograssive source material (i.e film). Taking interlaced source and deinterlacing to encode progressive is more likely to result in a low quality output because software deinterlacing techniques are average at best. If you are aiming to author this to DVD, leave it interlaced, and let you playback or display hardware deinterlace for you. It will do a much better job.

Thanks for that.

I deinterlace using VirtualDub filters, I never use Premiere's or TMPGEnc's.

If you are encoding for DVD, keep interlaced source interlaced, and progressive source progressive. Let the playback hardware do the work for you. I can guarantee you it will look better this way than if you software deinterlace.
